With the exception of WinRAR and Fritz Chess, the AMD FX-8350 was no more than 6% faster than the FX-8150 in any one of our tests, despite being clocked 11% faster (though we should keep in mind both processors feature a max turbo frequency of 4.2GHz). It was a similar situation when comparing the FX-6300 to the FX-6100, though the margins here were even slimmer as the Piledriver part is clocked just 6% higher.
